California Topographical Map ready for CNC cutting 3D model

Hi,I am a CNC enthusiast.This is a topographical map of the state of California. I made it from free data with free programs and a long procress editing. You can totally make your own if you have time to learn the long tedious process. Or buy this one please.

I do have all the states if you're looking for a different one. I can probably manage any region/country relatively easy. Please drop me a message if you're intrested.

If you purchase the file I will happily discuss milling strategies I have found effiecnt on my machine. ONLY STL FILEThank you UNA
